Diabetes is a chronic illness that requires continuing medical care and education in order to prevent acute complications and reduce the risks of developing other conditions related to uncontrolled blood glucose. These other conditions may include retinopathy, nephropathy, neuropathy, and cardiovascular disease.


Outpatient diabetes education and self-management training is a formalized, comprehensive outpatient program that teaches individuals who have been diagnosed with diabetes about their diagnosis and its treatment. Components of such programs typically include, but are not limited to the following: blood glucose self-monitoring; dietary requirements; exercise and its role in the management of diabetes; if necessary, instruction on the self-administration of pharmaceutical agents for the treatment of diabetes, as well as an insulin treatment plan.


Diabetes education programs provided in Iowa, according to State law, must be certified by the Iowa Department of Public Health.

Wellmark medical policies address the complex issue of technology assessment of new and emerging treatments, devices, drugs, etc.   They are developed to assist in administering plan benefits and constitute neither offers of coverage nor medical advice. Wellmark medical policies contain only a partial, general description of plan or program benefits and do not constitute a contract. Wellmark does not provide health care services and, therefore, cannot guarantee any results or outcomes. Participating providers are independent contractors in private practice and are neither employees nor agents of Wellmark or its affiliates. Treating providers are solely responsible for medical advice and treatment of members. Our medical policies may be updated and therefore are subject to change without notice.
